一、会员中心 - 整体功能梳理和路由配置
1. 整体功能梳理
- ①个人中心 - 个人信息和猜你喜欢数据渲染
- ②我的订单 - 各种状态下的订单列表展示
2. 路由配置(包括三级路由配置)
①准备个人中心模板组件 - src/views/Member/index.vue

个人中心交易管理
我的订单 .container { display: flex; padding-top: 20px; .xtx-member-aside { width: 220px; margin-right: 20px; border-radius: 2px; background-color: #fff; .user-manage { background-color: #fff; h4 { font-size: 18px; font-weight: 400; padding: 20px 52px 5px; border-top: 1px solid #f6f6f6; } .links { padding: 0 52px 10px; } a { display: block; line-height: 1; padding: 15px 0; font-size: 14px; color: #666; position: relative; &:hover { color: $xtxColor; } &.active, &.router-link-exact-active { color: $xtxColor; &:before { display: block; } } &:before { content: ''; display: none; width: 6px; height: 6px; border-radius: 50%; position: absolute; top: 19px; left: -16px; background-color: $xtxColor; } } } } .article { width: 1000px; background-color: #fff; } }②绑定个人中心二级路由 - src/router/index.js
import { createRouter, createWebHistory } from 'vue-router' // ... ... import Member from '@/views/Member/index.vue' const router = createRouter({ history: createWebHistory(import.meta.env.BASE_URL), routes: [ { path: '/', component: Layout, children: [ // ... ... { path: 'member', component: Member } ] }, { path: '/login', component: Login } ] }) export default router
③绑定路由跳转 - src/views/Layout/components/LayoutNav.vue
- a href="javascript:;" @click="$router.push('/member')">会员中心
④准备个人中心和我的订单三级路由组件
src/views/Member/components/UserInfo.vue
const userStore = {}{{ userStore.userInfo?.account }}

import { createRouter, createWebHistory } from 'vue-router' // ... ... import Member from '@/views/Member/index.vue' import UserInfo from '@/views/Member/components/UserInfo.vue' import UserOrder from '@/views/Member/components/UserOrder.vue' const router = createRouter({ history: createWebHistory(import.meta.env.BASE_URL), routes: [ { path: '/', component: Layout, children: [ // ... ... { path: 'member', component: Member, children: [ { path: 'user', component: UserInfo }, { path: 'order', component: UserOrder } ] } ] }, { path: '/login', component: Login } ] export default router
⑥绑定路由跳转关系 - src/views/Layout/components/LayoutNav.vue
二、会员中心-个人中心信息渲染
1. 使用Pinia数据渲染个人信息 - src/views/Member/UserInfo.vue
// 导入userStore import { useUserStore } from '@/stores/userStore' const userStore = useUserStore(){{ userStore.userInfo?.account }}
2. 封装 猜你喜欢 接口 - src/apis/user/js
// 获取 “猜你喜欢”数据 export const getLikeListAPI = ({ limit = 4 }) => { return instance({ url: '/goods/relevant', params: { limit } }) }
3. 渲染 猜你喜欢 数据 - src/views/Member/UserInfo.vue
import { ref } from 'vue' import { useUserStore } from '@/stores/user.js' import GoodsItem from '@/views/Home/components/GoodsItem.vue' import { getLikeListAPI } from '@/apis/user.js' const userStore = useUserStore() const likeList = ref([]) const getLikeList = async () => { const res = await getLikeListAPI({ limit: 4 }) likeList.value = res.result } getLikeList()猜你喜欢
三、会员中心 - 我的订单
1. 订单基础列表渲染
①封装订单接口 -src/apis/order.js
import instance from '@/utils/http.js' /* params: { orderState:0, page:1, pageSize:2 } */ export const getUserOrder = (params) => { return instance({ url: '/member/order', method: 'GET', params }) }
如果此处有出现以下问题,在src/utils/http.js里把timeout改大一点!!!
// 创建axios实例 const instance = axios.create({ baseURL: 'http://pcapi-xiaotuxian-front-devtest.itheima.net', timeout: 10000 })
2. tab切换实现
重点:切换tab时修改OrderState参数,再次发起请求获取订单列表数据
①绑定tab-change事件 -src/views/Member/components/UserOrder.vue
// tab切换 const tabChange = (type) => { params.value.orderState = type getOrderList() }
3. 分页逻辑实现
①使用列表数据生成分页(页数 = 总条数 / 每页条数)
②切换分页修改page参数,再次获取订单列表数据
src/views/Member/components/UserOrder.vue
import { ref } from 'vue' import { getUserOrder } from '@/apis/order.js' // tab列表 const tabTypes = [ { name: 'all', label: '全部订单' }, { name: 'unpay', label: '待付款' }, { name: 'deliver', label: '待发货' }, { name: 'receive', label: '待收货' }, { name: 'comment', label: '待评价' }, { name: 'complete', label: '已完成' }, { name: 'cancel', label: '已取消' } ] // 订单列表 const orderList = ref([]) const total = ref(0) const params = ref({ orderState: 0, page: 1, pageSize: 2 }) const getOrderList = async () => { const res = await getUserOrder(params.value) // console.log(res) orderList.value = res.result.items total.value = res.result.counts } getOrderList() // tab切换 const tabChange = (type) => { // console.log(type) params.value.orderState = type getOrderList() } // 页数切换 const pageChange = (page) => { console.log(page) params.value.page = page getOrderList() } 下单时间:{{ order.createTime }} 订单编号:{{ order.id }} 付款截止: {{ order.countdown }}

4. 会员中心 - 细节优化
①默认三级路由设置
效果:当路由path为二级路由路径member的时候,右侧可以显示个人中心三级路由对应的组件
src/router/index.js
import { createRouter, createWebHistory } from 'vue-router' // ... ... const router = createRouter({ history: createWebHistory(import.meta.env.BASE_URL), routes: [ { path: '/', component: Layout, children: [ // ... ... { path: 'member', component: Member, redirect: 'member/user', children: [ { path: 'user', component: UserInfo }, { path: 'order', component: UserOrder } ] } ] }, { path: '/login', component: Login } ], // ... ... }) export default router
②订单状态显示适配
思路:根据接口文档给到的状态码和中文的对应关系进行适配
四、拓展课 - SKU组件封装
1. 认识SKU组件
SKU组件的作用是为了让用户能够选择商品的规格,从而提交购物车,在选择的过程中,组件的选中状态要进行更新,组件还要提示用户当前规格是否禁用,每次选中都要产出对应的Sku数据
①创建项目 vite-sku-demo
清空无关的文件
②安装axios和sass
pnpm add sass -D
pnpm add axios
③初始化规格渲染 -src/Sku/Sku.vue
import { onMounted, ref } from 'vue' import axios from 'axios' // 商品数据 const goods = ref({}) const getGoods = async () => { // 1135076 初始化就有无库存的规格 // 1369155859933827074 更新之后有无库存项(蓝色-20cm-中国) const res = await axios.get('http://pcapi-xiaotuxian-front-devtest.itheima.net/goods?id=1369155859933827074') goods.value = res.data.result } onMounted(() => getGoods()) {{ item.name }} {{ val.name }} @mixin sku-state-mixin { border: 1px solid #e4e4e4; margin-right: 10px; cursor: pointer; &.selected { border-color: #27ba9b; } &.disabled { opacity: 0.6; border-style: dashed; cursor: not-allowed; } } .goods-sku { padding-left: 10px; padding-top: 20px; dl { display: flex; padding-bottom: 20px; align-items: center; dt { width: 50px; color: #999; } dd { flex: 1; color: #666; >img { width: 50px; height: 50px; margin-bottom: 4px; @include sku-state-mixin; } >span { display: inline-block; height: 30px; line-height: 28px; padding: 0 20px; margin-bottom: 4px; @include sku-state-mixin; } } } }
④在App.vue中导入渲染
import Sku from '@/Sku/Sku.vue'
2. 点击规格更新选中状态
核心思路:
- ①如何当前已经激活,就取消激活
- ②如果当前未激活,就把和自己同排的其他规格取消激活,再把自己激活
响应式数据设计:每一个规格项都添加一个selected字段来决定是否激活,true为激活,false为未激活。
样式处理:使用selected配合动态class属性,selected为true就显示对应激活类名
src/Sku/Sku.vue
import { onMounted, ref } from 'vue' import axios from 'axios' // 商品数据 const goods = ref({}) const getGoods = async () => { // 1135076 初始化就有无库存的规格 // 1369155859933827074 更新之后有无库存项(蓝色-20cm-中国) const res = await axios.get('http://pcapi-xiaotuxian-front-devtest.itheima.net/goods?id=1369155859933827074') goods.value = res.data.result } onMounted(() => getGoods()) // 切换选中状态 const changeSelectedStatus = ( item, val ) => { // item: 同一排的对象,val:当前点击项 if ( val.selected ) { val.selected = false } else { item.values.forEach( val => val.selected = false ) val.selected = true } } {{ item.name }} {{ val.name }}
3. 点击规格更新禁用状态 - 生成有效路径字典
规格禁用的判断依据是什么?
核核心原理:当前的规格Sku,或者组合起来的规格Sku,在skus数组中对应项的库存为零时,当前规格会被禁用,生成路径字典是为了协助和简化这个匹配过程。
实现步骤:
- ①根据库存字段得到有效的Sku数组
- ②根据有效的Sku数组使用powerSet算法得到所有子集
- ③根据子集生成路径字典对象
①powerSet算法 - src/Sku/power-set.js
export default function bwPowerSet (originalSet) { const subSets = [] // We will have 2^n possible combinations (where n is a length of original set). // It is because for every element of original set we will decide whether to include // it or not (2 options for each set element). const numberOfCombinations = 2 ** originalSet.length // Each number in binary representation in a range from 0 to 2^n does exactly what we need: // it shows by its bits (0 or 1) whether to include related element from the set or not. // For example, for the set {1, 2, 3} the binary number of 0b010 would mean that we need to // include only "2" to the current set. for (let combinationIndex = 0; combinationIndex getGoods()) // 切换选中状态 const changeSelectedStatus = ( item, val ) => { // item: 同一排的对象,val:当前点击项 if ( val.selected ) { val.selected = false } else { item.values.forEach( val => val.selected = false ) val.selected = true } } // 生成有效路径字典对象 const getPathMap = (goods) => { const pathMap = {} // 1. 根据skus字段生成有效的sku数组 const effectiveSkus = goods.skus.filter(sku => sku.inventory > 0) // 2. 根据有效的sku使用powerSet算法得到所有子集 effectiveSkus.forEach(sku => { // 2.1 获取匹配的valueName组成的数组 const selectedValArr = sku.specs.map(val => val.valueName) // 2.2 使用算法获取子集 const valueArrPowerSet = powerSet(selectedValArr) // 3. 把得到子集生成最终的路径字典对象 valueArrPowerSet.forEach(arr => { // 初始化key 数据join -> 字符串 对象的key const key = arr.join('-') // 如果已经存在当前key了,就往数组中直接添加skuId, 如果不存款key,直接做赋值 if( pathMap[key] ) { pathMap[key].push(sku.id) } else { pathMap[key] = [sku.id] } }) }) return pathMap }
4. 点击规格更新禁用状态 - 初始化规格禁用
思路:遍历每一个规格对象,使用name字段作为key去路径字典pathMap中做匹配,匹配不上则禁用
怎么做到显示上的禁用呢?
- ①通过增加disabled字段,匹配上路径字段,disable为false;匹配不上路径字段,disabled为true
- ②配合动态类名控制禁用类名
import { onMounted, ref } from 'vue' import axios from 'axios' import powerSet from './power-set.js' // 商品数据 const goods = ref({}) const getGoods = async () => { // 1135076 初始化就有无库存的规格 // 1369155859933827074 更新之后有无库存项(蓝色-20cm-中国) const res = await axios.get('http://pcapi-xiaotuxian-front-devtest.itheima.net/goods?id=1135076') goods.value = res.data.result const pathMap = getPathMap(goods.value) console.log(pathMap) initDisabledStatus(goods.value.specs, pathMap) } onMounted(() => getGoods()) // ... ... // 初始化禁用状态 const initDisabledStatus = (specs, pathMap) => { specs.forEach(spec => { spec.values.forEach(val => { if( pathMap[val.name] ) { val.disabled = false } else { val.disabled = true } }) }) } {{ item.name }} {{ val.name }}
给的例子中该商品的所有规格的库存都为0,因为三张图片都会显示禁用状态!!!
5. 点击规格更新状态 - 点击时组合禁用更新
思路(点击规格时):
①按照顺序得到规格选中项的数组 ['蓝色', '20cm', undefined]
②遍历每一个规格
- 把name字段的值填充到对应的位置
- 过滤掉undefined项使用join方法形成一个有效的key
- 使用key去pathMap中进行匹配,匹配不上,则当前项禁用
// ... ... // 商品数据 const goods = ref({}) let pathMap = {} const getGoods = async () => { // 1135076 初始化就有无库存的规格 // 1369155859933827074 更新之后有无库存项(蓝色-20cm-中国) const res = await axios.get('http://pcapi-xiaotuxian-front-devtest.itheima.net/goods?id=1369155859933827074') goods.value = res.data.result pathMap = getPathMap(goods.value) console.log(pathMap) // 初始化更新按钮状态 initDisabledState(goods.value.specs, pathMap) } // ... ... // 获取选中项的匹配数组 const getSelectedValues = (specs) => { const arr = [] specs.forEach(spec => { // 目标:找到values中的selected为true的项,然后把它的name字段添加到数组对应的位置 const selectedVal = spec.values.find(value => value.selected) arr.push(selectedVal ? selectedVal.name : undefined) }) return arr } // 切换时更新禁用状态 const updateDisabledStatus = (specs, pathMap) => { // 约定:每一个按钮的状态由自身的disabled进行控制 specs.forEach((item, i) => { const selectedValues = getSelectedValues(specs) item.values.forEach(val => { if(val.selected) return const _selelctedValues = [...selectedValues] _selelctedValues[i] = val.name const key = _selelctedValues.filter(value => value).join('-') // 路径字典中查找是否有数据,有->可以点击;没有->禁用 val.disabled = !pathMap[key] }) }) }
6. 产出有效的SKU信息
1. 什么时有效的SKU?
2. 如何判断当前用户已经选择了所有有效的规格?
已选择项数组['蓝色', '20cm', undefined]中找不到undefined,那么用户已经选择了所有的有效规格,此时可以产出数据。
3. 如何获取当前的SKU信息对象?
把已选择项数组拼接为路径字典的key,去路径字典pathMap中找即可。
// 切换选中状态 const changeSelectedStatus = ( item, val ) => { if(val.disabled) return // item: 同一排的对象,val:当前点击项 if ( val.selected ) { val.selected = false } else { item.values.forEach( val => val.selected = false ) val.selected = true } // 点击按钮时更新 updateDisabledStatus(goods.value.specs, pathMap) // 产出SKU对象数据 const index = getSelectedValues(goods.value.specs).findIndex(item => item === undefined) if(index > -1) { // 找到, 信息不完整 console.log('找到了, 信息不完整') } else { // 没找到,信息完整,可以产出 console.log('没找到,信息完整,可以产出') // 获取sku对象 const key = getSelectedValues(goods.value.specs).join('-') const skuIds = pathMap[key] console.log(skuIds) // 以skuId作为匹配项去goods.value.skus数组中找 const skuObj = goods.value.skus.find(item => item.id === skuIds[0]) console.log('sku对象为', skuObj) } }
完结撒花!!!
